FLD 3D - Future Lines of Demarcation Indicator

═══════════════════════════════════════════════════
THEORETICAL FOUNDATION
═══════════════════════════════════════════════════

This indicator implements Future Lines of Demarcation (FLD), a key concept from J.M. Hurst's cyclic analysis theory. FLDs are price-based lines displaced forward in time by half the wavelength of a dominant cycle, creating a predictive framework for price movement analysis.

The core principle: when price crosses an FLD line, it indicates a potential change in the current cycle phase. FLDs act as dynamic support/resistance levels that "anticipate" where price should be based on the dominant cycle's rhythm.

═══════════════════════════════════════════════════
CALCULATION METHODOLOGY
═══════════════════════════════════════════════════

The indicator calculates three FLD lines:

1. FLD HIGH: Takes the bar's high price and shifts it forward by offset bars
2. FLD LOW: Takes the bar's low price and shifts it forward by offset bars
3. FLD MEDIAN: Calculates a median price using the selected method, then shifts forward

The offset is calculated as: offset = Period / 2

This displacement represents the half-cycle concept: if a cycle has a period of 48 bars, the FLD will be displaced 24 bars into the future. This creates a "lead" indicator that shows where price should theoretically be based on the cycle's wave pattern.

PRICE METHODS AVAILABLE:
- HL2: (High + Low) / 2 - Simple midpoint
- HLC3: (High + Low + Close) / 3 - Weighted with close
- HLCC4: (High + Low + Close + Close) / 4 - Close has double weight
- OHLC4: (Open + High + Low + Close) / 4 - Full bar average
- VWAP-like: Volume-weighted high/low average
- True Range: Uses previous close for range calculation

═══════════════════════════════════════════════════
AUTO-PERIOD ADJUSTMENT FEATURE
═══════════════════════════════════════════════════

The indicator includes multi-timeframe adaptation logic. When "Auto Period" is enabled:

1. Detects current chart timeframe (minutes, hours, days, weeks)
2. Compares it to the reference timeframe setting
3. Calculates adjustment ratio: Reference TF / Current TF
4. Applies ratio to base period: Adjusted Period = Base Period × Ratio

Example: If Base Period = 48, Reference TF = 60min, Current chart = 15min
→ Ratio = 60/15 = 4
→ Adjusted Period = 48 × 4 = 192 bars

This ensures the indicator tracks the same real-time cycle length across different chart timeframes, maintaining consistency in cycle analysis.

VISUAL COMPONENTS
═══════════════════════════════════════════════════

- RED LINE: FLD High (upper boundary)
- BLUE LINE: FLD Low (lower boundary)
- ORANGE LINE: FLD Median (centerline)
- GRAY AREA: Fills between High and Low FLDs
- RIGHT LABEL: Shows FLD identifier and period used (asterisk indicates auto-adjustment)

All lines extend into the future by the calculated offset, creating a "projection zone" ahead of current price.
